The fit on Brooks shirts and apparel is hit or miss. A small, fitted jacket should be snug on me, but Brooks apparel is often a little larger or loose. Becuase of this I ordered an extra small, and after washing it fit very well and snug, though the sleeves were just a little short. Overall, its a nice, stylish jacket to wear outdoors (40-60F), and should be good to jog in above 30F. Definitely recommend for at lease a nice track jacket to wear out and about.

This is a sharp jacket and you will be noticed. I wear it to work, gym and before/after runs. I purchased the black/white jacket and it matches the Spartan II pants and Vapor Dry 3D Stadium Pant nicely. I normally wear small and purchased a small. It is slightly tighter than other jackets, but fits fine and can run comfortably. If you're looking for a jacket to layer with, order the next size.

I use this jacket both before and after runs. I use it to keep warm on colder days but I don't use it during runs because it is too cold and heavy for that purpose. I have been told that it's a very stylish jacket that looks good as an everyday wear.

A nice warm track jacket. Not wind or water proof, but have found it very comfortable both post-race and wearing around town. I find it a little too warm to go running in, but just right for early fall hiking.

I love this jacket. Picked one up at last year's MCM and I wear it constantly. It's warm enough that I was comfortable on all but the coldest days this winter (there's only so much a jacket can do with a high of -1) but still not too much for a crisp spring day. Great looking jacket and great fitting as well. Has a snug, fitted feel, but the jacket fits true to size. I don't run in jackets, so this is a casual wear article for me.

This jacket is a little heavier than I thought it would be. Keeps you warm in 30 deg running conditions, and as a spring jacket, but if using to run in 40's and above, you will overheat like crazy. Also fits a little tight in the shoulders and upper back area. Great jacket to wear as a warm up, or to the kids soccer game!
